My camera class with pinch to zoom

I made a Camera class for my game since i couldn't find one i liked. I'm really pleased with how it turned out so i decided to share it here. The camera can follow an object, be dragged around with your finger and zoom with pinching.
How to use:
If you want the camera to follow something, like the player:
If you just want to drag around the camera with your finger:
So basicly make a sprite that is your world or your scene, create the camera with the sprite in the constructor.
Then add every object as child to that sprite.
And run Camera:update() on every frame.
Right now the camera has no limit on how far it can go in any direction, if you add that or any other improvement please post it here
How to use:
If you want the camera to follow something, like the player:
local world = Sprite.new() local camera = Camera.new(world) camera:setFollowMode() local player = Sprite.new() function onEnterFrame() camera:setTarget(player:getPosition()) camera:update() end world:addEventListener(Event.ENTER_FRAME, onEnterFrame) world:addChild(player) stage:addChild(world) |
local world = Sprite.new() local camera = Camera.new(world) --set the starting place of the camera if you want camera:setTarget(100, 100) --addsome random game object local Ball = Bitmap.new(Texture.new("ball.png")) function onEnterFrame() camera:update() end world:addEventListener(Event.ENTER_FRAME, onEnterFrame) world:addchild(Ball) stage:addChild(world) |
Then add every object as child to that sprite.
And run Camera:update() on every frame.
Right now the camera has no limit on how far it can go in any direction, if you add that or any other improvement please post it here
